Description
本發明關於扁平鑰匙輪廓,其用於鎖鑰匙系統,其中,在鎖心中設置用於與鑰匙輪廓對應的扁形鑰孔。 The present invention relates to a flat key profile for a lock-key system, wherein a flat keyhole for a corresponding key profile is provided in the lock core.
詞語扁平鑰匙亦關於肋輪廓鑰匙或鎖肋輪廓鑰匙,亦即,肋凸出超過鑰匙的側面的輪廓。 The term flat key also refers to a rib profile key or a lock rib profile key, ie a profile in which the rib protrudes beyond the sides of the key.
鑰匙由於各種原因被複製或拷貝,其中,在合法和非法之間做出區別。 Keys are copied or copied for various reasons, among which a distinction is made between legal and illegal.
透過使用涉及受保護的輪廓(亦即,已獲得專利保護或新型保護的這種輪廓)的這種鑰匙輪廓,複製變得困難或至少應該變得困難。 By using such a key profile involving a protected profile, ie one that has patent or novel protection, reproduction becomes difficult, or at least should become difficult.
這種鑰匙可選擇經由鑰匙製造商或授權的鑰匙服務進行重新排序。 Such keys can optionally be reordered via the key manufacturer or an authorized key service.
相反地,已知的是,處於可使用複製機器來製造出具有受保護的輪廓本身的複製鑰匙的地位的鑰匙服務。然而,存在並非如此簡單的輪廓,使得使用簡化的方式來近 似實際輪廓。 Conversely, there are known key services in a position where a replica machine can be used to produce a replica key with the protected profile itself. However, there are not so simple outlines that using a simplified approach Like the actual outline.
例如,這涉及橫向輪廓槽的形狀。 This concerns, for example, the shape of the transverse profile grooves.
市面上的複製機器使用薄的圓形鋸片(saw blade),其僅能夠執行矩形切口。當複製需要V形切口時,僅能夠執行矩形切口來替代。 Commercially available duplication machines use thin circular saw blades, which are only capable of performing rectangular cuts. When a V-shaped cut is required for replication, only a rectangular cut can be performed instead.
現在,本發明的目的在於使鑰匙輪廓之基於機器的複製能力變得困難。 It is now an object of the present invention to make machine-based replication of key profiles difficult.
根據本發明,此目的藉由用於鎖鑰匙系統的扁平鑰匙輪廓來實現,其中,在鎖心中設置用於與鑰匙輪廓對應的扁形鑰孔,其中,鑰匙軸的鑰匙輪廓具有面對鑰匙的後側的輪廓區段、以及面對鑰匙盒的下部輪廓區段,從鑰匙盒開始,在鑰匙軸平面中設置在下部輪廓區段中突出的凹口,在鑰匙軸的一側面中於下部輪廓區段中設置三角形之超出中心線(paracentric)的輪廓槽2,其延伸超過鑰匙軸的中心平面,在鑰匙軸的相對側面上設置三角形輪廓槽,其被佈置在相對的超出中心線的輪廓槽的上方或下方,並具有與相對的超出中心線的輪廓槽的輪廓底部相距一水平距離的輪廓底部,
相對於相對的輪廓槽,超出中心線的輪廓槽的佈置為使得垂直於鑰匙軸平面從超出中心線的輪廓槽的上部支腳或下部支腳與鑰匙側面的交會點延伸朝向相對的輪廓槽的假想線與從相對的輪廓槽的上部支腳或下部支腳與鑰匙側面的交會點延伸直到超出中心線的輪廓槽的假想線之間具有垂直距離。
According to the invention, this object is achieved by a flat key profile for a lock-key system, wherein a flat keyhole is provided in the lock core for a corresponding key profile, wherein the key profile of the key shaft has a rear face facing the key. The side profile section and the lower profile section facing the key box, starting from the key box, a recess protruding in the lower profile section is provided in the key shaft plane, in the lower profile section in one side of the key shaft A
在附屬請求項中闡述有利的配置。 An advantageous configuration is stated in the attached claim.
所使用的是兩個輪廓特徵,其彼此相對並具有三角形(V形)配置。輪廓特徵為對稱的,且在其底部具有半徑。 What is used are two profile features that are opposite each other and have a triangular (V-shaped) configuration. The profile feature is symmetrical and has a radius at its base.
當兩個相對的特徵現在佈置為,例如,在輪廓被矩形地銑削時非常靠近彼此時,鑰匙將在此區域中斷裂。最小重疊應位在0.2mm,且最大殘餘厚度應為0.3mm。為了能夠以經濟的方式產生三角形切口(輪廓特徵),較深的切口應具有a=110°的角度。 When two opposing features are now arranged, for example, very close to each other when the profile is milled rectangularly, the key will break in this area. The minimum overlap shall be 0.2mm and the maximum residual thickness shall be 0.3mm. In order to be able to produce triangular cuts (profile features) in an economical way, the deeper cuts should have an angle of a=110°.
必須具有相對偏離關係的至少兩個切口。從較深的切口開始,更多切口因此必須出現在此較深的切口的“上方”或“下方”。 There must be at least two cuts in relatively offset relationship. Starting with a deeper cut, more cuts must therefore appear "above" or "below" this deeper cut.
如上所述,由於具有矩形銑片的複製機器無法產生V形輪廓槽,則輪廓槽必須被矩形地銑削,以必然地變得更寬。 As described above, since replication machines with rectangular milling blades cannot produce V-shaped profile grooves, the profile grooves must be milled rectangularly to necessarily become wider.
然而,由於根據本發明必須遵守更多佈置上的相互關係或特徵,鑰匙軸因此在某些區域變得太薄,使得鑰匙軸在複製過程中或最遲在使用時斷裂。 However, since according to the invention more interrelationships or features in the arrangement have to be observed, the key shaft thus becomes too thin in certain areas, so that the key shaft breaks during the reproduction process or at the latest during use.
因此,機械輪廓複製機器的缺點被利用,使得複製的 鑰匙變得無法使用。 Therefore, the disadvantages of mechanical profile copying machines are exploited so that the The key becomes unusable.
同樣地,藉由絲狀物(filament)的複製-3D列印,由於斜面而顯然變得更加困難,這是因為斜面在此只能在階級中被產生。 Likewise, with replication of filaments - 3D printing, it is obviously more difficult due to bevels, since bevels here can only be created in layers.

With respect to the oppositely arranged contour grooves, the contour grooves beyond the centerline are arranged so that there is a

Therefore, horizontal and vertical distances are established here. The maximum
從較深的切口的角度a應相當於110°。半徑R應相當於0.2mm。 The angle a from the deeper cut should correspond to 110°. The radius R should be equivalent to 0.2mm.
可根據距離8及9自由地選擇角度b。該角度b為可變化的,且130°b100°。
The angle b can be freely selected according to the
較佳地,切口(輪廓特徵)應位在鑰匙的“下部”區域中,亦即,從鑰匙盒開始的凹口。 Preferably, the cutout (profile feature) should be located in the "lower" area of the key, ie, the notch from the key box.
三角形之超出中心線的輪廓槽(2)具有在上部支腳中的至少一肩部(13),其與在相對的在上部之三角形輪廓槽(3)的下部支腳中的肩部(10)相關聯,或者在下部支腳中的肩部(12),其與在相對的在下部之三角形輪廓槽(4)的上部支腳中的肩部(11)相關聯,其中,該肩部開始於該三角形輪廓槽與鑰匙外表面的假想交叉點,並具有該三角形輪廓槽的1/3的最小深度。 The triangular contoured groove (2) beyond the centerline has at least one shoulder (13) in the upper leg which is opposite to the shoulder (10) in the lower leg of the upper triangular contoured groove (3) ), or the shoulder (12) in the lower leg, which is associated with the shoulder (11) in the upper leg of the opposite triangular profile groove (4) in the lower part, wherein the shoulder Starts at the imaginary intersection of the triangular profile groove with the outer surface of the key and has a minimum depth of 1/3 of the triangular profile groove.
該等肩部(10-13)具有對稱或非對稱的深度。 The shoulders (10-13) have a symmetrical or asymmetrical depth.
